我如何生成文本并自行比较特定文本

Question

I do not know how to work on the following problem (How can I print each letter of the entered word at the end of each randomly generated word and the single letter of the entered word can be repeated more than once and take the letters from the entered word randomly while ensuring that all the letters of the entered word are taken And print them out)

Example:

input:

name = "adel"

output:

lkjljl a                     
sdada l               
lkkjlkj l               
werwrew d           
oioiu e

What I have so far:

public void Gen(String name) {
    Random r = new Random();
    String alphabet = "abcdefghijklmnopqrstuvwxyz";

    for (int j = 0; j < name.length(); j++) {
        for (int i = 0; i < alphabet.charAt(r.nextInt(alphabet.length())) % 30; i++) {
            System.out.print(alphabet.charAt(r.nextInt(alphabet.length())));
        }
        char g = name.charAt(j);
        System.out.println(g);

    }
}

Answer 1

In your second for loop,

for (int i = 0; i < alphabet.charAt(r.nextInt(alphabet.length())) % 30; i++)

alphabet.charAt(r.nextInt(alphabet.length())) gives you String , not int , so there's an error there. You can just remove alphabet.charAt() .

Also, On your print statement, it generate another random number, which can be different than the one in the second for loop.

Answer 2

public void Gen(String name) {
    Random r = new Random();
    String alphabet = "abcdefghijklmnopqrstuvwxyz";

    for (int j = 0; j < name.length(); j++) 
        {
            System.out.print(alphabet.charAt(r.nextInt(alphabet.length())));

              char g = name.charAt(j);
           System.out.println(g);
        }



}
